CHIMNEY-COWL.

SPECIFICATION forming part of Letters Patent No. 463,202, dated November17, 1891.

Application liled June l1, 1891 Serial No. 395,859. y(No model.)

To @ZZ whom t may concern.-

Be it known that I, IGNATIUS C. SCHNEIDER, of Sleepy Eye, inthe countyof Brown and State of Minnesota, have invented a certain ImprovedChimney-Cowl, of which the following is a specification.

My invention relates to chimney caps or cowls adapted to revolve and tocreate av strong draft in the chimney, and especially to particularconstructions thereof.

The object of the invention is to provide a cowl having a n umher ofpoints of superiority over those now in-use, among which are durability,noiselessness, and neat, cheap, simple, and symmetrical construction.

My invention consists in a cylindrical cap portion provided with conicalends and with a number of substantially tangential smoke outlets orspouts, and means in combination therewith for supporting the same, sothat the same will rotate freely and noiselessly.

Further, the invention consists in various constructions andcombinations hereinafter described, and particularly pointed out in theclaims.

My invention will be more readily initierstood by reference to theaccompanying drawings, in which- Figure 1 is a side view of achimney-cap embodying my invention. Fig. 2 Vis an enlarged sectionalView thereof. Fig. 3 is a section thereof on the line :n x of Fig. l.Fig. 4 is a detail view showing` the supporting device for the cap. Fig.5 is an enlarged view ot' the spider secured on the upper end of therod. Figs. 6, 7, 8, and 9 are detail views of the pivot or yoke armemployed in connection with the upright pivotarm.

As shown in lthe drawings, the cap has a cylindrical part 2, having anumber of slots or openings 3 in its walls, from which the tangentialspouts or ducts lead, as most clearly shown in Figs. l and 3. Theforward sides of these spouts, forming obtuse angles with the part 2,are made by bendingout the metal cutaway to form the slots. Theotherthree sides of the spouts are formed of a separate piece of sheet metal.The top and bottom of the device are formed by the upper cone 5 havingedges 6 fitting down over the cylinder 2 and by the lower truncated cone7 having a similar edge or flange 8. The supporting- `upon the upper endof t-he rod l1.

pipe 9 extends up through the hole in the bottom of the cone 7 and hasits lower end secured in the chimney-top 10. Within the cap and inconnection with the pipe 9 is provided the device forsupporting the cap,which, it willbe seen, is extended over the sleeve and The spider havingarms 12 may be secured thereto and riveted to theinside of the cone 5.The sleeve 13 is secured in the pipe 9. The narrow bridge 14C isarranged in the top of this sleeve and provided with the spur 15,extending up into the cone 1G, provided on the lower. end ot' the rod11.In this way the cap is pivoted. The rod 1l is held against a sidewise ora vertical movement by the cross arms or yokes 17 anddlS, secured on theupright rods 19 and 20, respectively, extending up from fastenings onthe sleeve 13. A collar or enlargement 2l is arranged on the rod 11 justbeneath the yoke 17 to prevent a vertical movement ot' the rod 11, Whilethe yoke 1S is arranged just The yokes may be made of solid castings;but I prefer to construct the same as shown in the last four figures ofthe drawings. The ends of the yoke-pieces are provided with eyelets 22,adapted to receive the ends of the rods, which may be bolted or rivetedtherein, and the yoke arms or bars are made in two parts, one hinged onthe other, the hinged part 23 being secured thereto by suitable pivotbolts or rivets 24. The two parts of the yoke are provided withsemicircular notches adapted to receive a halt-section 25 of theremovable bearings, which bearings are usually of cork or soft wood orother elastic material, in which the rod may rotate without making anynoise. These bearing-blocks are provided with the grooves 2G, wherebythey tit closely into the There the cap is small, the movable part 23 ofthe yoke is ordinarily longer than indicated in the drawings.

In use the wind strikes upon theV sides of the spouts and rotates theshaft, thereby causing suction in the chimney-flue. The cones upon thetop and bottom act as defiectors and give the device a neat and pleasingappearance. The pipe 9 may be of any desired, length or may be dispensedwith and the sleeve 13 secured directly in the chimney-top.

IOO

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, in a device of the classdescribed, of the cylindrical portion and the cone and portions oi' thecap with substair tially tangential spouts arranged in connectiontherewith, a sleeve 13, a Vertical rod 11, to the upper end of which thecap is secured, a spur 15, projecting into a cone-bearing arranged onthe lower end of the rod, upright rods 19 and rods 20, and yoke or crosspieces arranged in connection therewith and elnsecured on said sleeve,cross pieces or yokes arranged between the ends thereof, said yokesbeing made each in two parts adapted to be locked together, separatebearing-blocks 25, arranged in connection therewith and adapted toengage said rod 11, and a collar 21, provided thereon and adapted tolimit the Vertical moveinent of the rod 11, as and for the purposespecified. i

In testimony whereof I have hereunto set my hand this 4th day of June,1891.
